IMPROVEMENT' iN BOBBINS FOR iSPINNiNGfNiACHINES.

i Specification forming part of Letters Patent No. 142,245, dated August26, 1873; application filed .I une 2, 1873.

To all whom it may concern: v

Be it known that I, PERLEY LAFLIN, of Warren, of the county of Worcesterand State of Massachusetts, have invented a new and useful Improvementin the Bobbins and Spin-A dles of Spinning-Machines 5 and do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawings, of which- Figure l is avertical section of a bobbin and spindle provided with my invention.

Fig. 2 is a top View, and Fig 3 a side eleva-` tion, of the spindle.Fig. 4 is a vertical section of the bobbin. Fig. 5 is a view of thelower end of the bobbin. Fig. 6 is a perspec tive representation of oneform of the yielding stopA arranged in the circular groove of the baseof the bobbin. Fig. 7 is another such representation of another form ofit.

In the drawings, A denotes the spindle, and

l B the bobbin, O being the part on which the bobbin usually rests. Suchpart, C, has usually been provided with one or more studs,

` a a, to enter a circular groove made in the -the bobbin to be split orbroken at or in the head. Other injurious consequences are liablel toresult, especially the throwing up or l rising of the bobbin on thespindle.

In carrying out my invention or improvement, I employ with the bobbin ayielding stud, substantially as herein described, such as will hold thebobbin sufficiently to the spindle for the latter to revolve thebobbinfor taking up the yarn, and-still yield or give away under anysudden or undue strain, so as to allow the bobbin to turn on thespindle. To this end, and as one mode of carrying out my invention, Iarrange inthe groove c, Ain the base of the bobbin, a` circularly-curvedwire or elastic spring, D, which, at either or each end, may be bent'outward at aright angle, as shown, so as to constitute a shoulder orstud. This wire, which I term a yielding stop, has its outer peripherysprung into close contact with the periphery of the groove, which may bechanneled to receive it. The spindle or the bobbin seat O thereof Ifurnish, as usual, with one or two studs, a a, rigidly fixed to it.

It will readily be seen that, under sudden starting or stopping of thespinning-machine, and under strain on the elastic spring or curved WireD, the latter will give way or yield, and in so doing not split or breakthe bobbin. A

Instead of the groove, with the yielding stop D, being arranged in thebobbin-base, a rigid stop may be projected therefrom to cooperate with ayielding stop, such as above described, applied to 'the spindle or 'theseat O thereof, which, for such purpose, may be grooved and thestop bearranged in the groove, in manner similar to the bobbin shown .in Figs.l and 4.

I claim- The yielding stop D, substantially as described, applied to thebobbin B, or to the stationary bobbin-seat C iixed to the spindle, allbeing and operating essentially as specified.

PEELEY is LAELIN. mark.
